Method and disc drive for providing a content entity from a storage disc

1. Method for providing a content entity from a storage disc, the method comprising: providing an entity selection menu for reproduction from a storage disc, the storage disc comprising the content entity to be provided and at least one further content entity, wherein each content entity comprises a main menu and at least one submenu accessible via the main menu, and wherein the storage disc further comprises the entity selection menu, wherein the entity selection menu comprises a link to the main menu of the content entity to be provided and a link to the main menu of the further content entity; receiving a selection of the content entity to be provided based on the entity selection menu, the selection indicating a selected content entity; detecting that the storage disc comprises a plurality of content entities; mapping a pre-defined start address required by a player host software to a different start address of the storage disc associated with the main menu of the selected content entity to be provided, wherein the mapping is based on the detecting that the storage disc comprises a plurality of content entities; and providing the selected content entity for reproduction based on the different start address, the step of providing comprising subsequent to receiving a selection of the content entity, emulating an ejection of the storage disc and an insertion of another disc by providing an ejection signal to the player host software and by providing an insertion signal to the player host software, wherein the different start address is used for providing the selected content entity to the player host software after the emulated insertion of the other disc.

2. Method according to claim 1 , further comprising: emulating an ejection of the other disc and an insertion of the storage disc by receiving an ejection signal from the player host software and by providing an insertion signal to the player host software, wherein the pre-defined start address is used after the emulated insertion of the storage disc; and providing again the entity selection menu for reproduction.

3. Method according to claim 1 , wherein no content entity stored on the storage disc comprises a link to the entity selection menu.

4. Method according to claim 1 , wherein the storage disc comprises a file structure, wherein the main menu of the content entity to be provided, the main menu of the further content entity and the entity selection menu are stored in different files, wherein the different files of the menus comprise all the same file name, wherein the file of the main menu of the content entity to be provided is associated with the different start address, and wherein the file of the entity selection menu is associated with the pre-defined start address.

5. Method according to claim 1 , wherein detecting that the storage disc contains a plurality of content entities is based on detecting that the selection of the content entity to be provided results in an address jump to an address outside an address range of a content of the storage disc associated with the entity selection menu.

6. Method according to claim 1 , wherein the storage disc comprises a status parameter, wherein the detection that the storage disc contains a plurality of content entities is based on the status parameter.

7. Method according to claim 1 , wherein the content entity to be provided is created for being stored on a single content entity disc, wherein a single content entity disc contains only one content entity, wherein the content entity is stored on the storage disc without adaptation for being stored on the storage disc comprising a plurality of content entities.

8. Method according to claim 1 , wherein mapping the pre-defined start address to the different start address comprises replacing the pre-defined start address by a different start address stored on the storage disc, wherein a storage location of the different start address is located within a storage region of the content associated with the entity selection menu, or comprises adding the pre-defined start address and an address offset, wherein the address offset is stored on the storage disc, wherein a storage location of the address offset is located within a storage region of a content associated with an entity selection menu.

9. Method according to claim 1 , wherein a content entity stored on the storage disc comprises a movie.

10. Method according to claim 1 , wherein each content entity stored on the storage disc comprises a movie.

11. Disc drive for providing a content entity from a storage disc, the disc drive comprising: an input interface configured to receive a selection of a content entity to be provided based on an entity selection menu, the storage disc comprising the content entity to be provided and at least one further content entity, wherein each content entity comprises a main menu and at least one submenu accessible via the main menu, and wherein the storage disc further comprises the entity selection menu, wherein the entity selection menu comprises a link to the main menu of the content entity to be provided and a link to the main menu of the further content entity, wherein, the selection indicates a selected content entity; a multi-entity detector configured to detect that the storage disc contains a plurality of content entities; an address mapper configured to map a pre-defined start address required by a player host software to a different start address of the storage disc associated with the main menu of the selected content entity to be provided, wherein the mapping is based on the detection that the storage disc comprises a plurality of content entities; and an output interface configured to provide the entity selection menu for reproduction and configured to provide the selected content entity for reproduction based on the different start address, wherein the output interface is configured to emulating an ejection of the storage disc and an insertion of another disc by providing an ejection signal to the player host software and by providing an insertion signal to the player host software, subsequent to the input interface receiving a selection of the content entity, wherein the output interface is configured to use the different start address for providing the selected content entity to the player host software after the emulated insertion of the other disc.

12. Non-transitory storage medium having stored thereon a computer program with a program code for performing the method according to one of claims 1 to 10 , when the computer program runs on a computer or a microcontroller.
